Accelerate your time to Oracle RAC cloud migration with Cambridge Technology, an APN advanced consulting partner with AWS Oracle competency. For the full list of oracle program supported we can check this document. This test migrates the DR environment RAC prddg from on-premises site B to VMware Cloud on AWS. Amazon Web Services (AWS) offers you the ability to run your Oracle Database in a cloud environment. This test also demonstrated the use of VM-to-VM Anti Affinity rules to ensure RAC VM’s vmcrac01 and vmcrac02 must not run on the same host to ensure continued HA. More details about this change can be found here. Per the Oracle RAC on Amazon EC2 article in the AWS solutions library, there is no native support, but running RAC on AWS is nevertheless possible by using a third-party software component. Thus, Oracle RAC cannot be licensed in any Third-Party Cloud, including Amazon AWS and Microsoft Azure, regardless of the technology or container used to operate Oracle RAC in those environments. Licensing Oracle RAC on AWS is tricky, because Oracle wants to deter people from running it in any cloud environment but their own. The option you use depends upon the reason RAC is being used. Whether you choose to run a self-managed Oracle Database on Amazon EC2 or the fully managed Amazon RDS for Oracle, following the best practices discussed in this This test case focuses on deploying a new 2-node RAC vmcrac with RAC VM’s vmcrac01 and vmcrac02 on VMware Cloud on AWS as per Oracle on VMware best practices and Oracle RAC on VMware deployment guide. Oracle RAC != AWS. The shared vmdk’s need to be added at the same SCSI position on all RAC VM’s and provisioned as Thin provisioned with multiwriter attribute set. Oracle E-Business Suite RAC deployed on VMware Cloud on AWS SDDC will benefit from the advantages of high availability, scalability, operational procedures and improved performance. The Network Section above shows an OraclePrivate logical network which is created for the Oracle RAC Private Interconnect traffic. This post describes a Better Together demonstration VMware and AWS presented at VMworld 2017 using an Oracle RAC Database for high-availability zero-downtime client connection failover, supporting a Django-Python application running in a Native AWS Elastic Beanstalk environment. To a database administrator or developer, there are no differences between the two environments. You can remove a processor from a bi-socket to become a one-socket server, and then build a cluster running RAC in Standard Edition with 2 of those nodes. The rest of the steps from a provisioning or compute or storage perspective is no different than on-premises. All best practices for Oracle workloads on VMware SDDC were followed in accordance with the Oracle Databases on VMware Best Practices Guide here. When planning to deploy your critical oracle databases in the aws cloud high availability is one of the most critical criteria.
